Diamond Education

Diamond Carat Education

Carat, sometimes abbreviated as “ct.”, defines the weight, not the size of a diamond. Two diamonds both weighing 2 carat may appear to be different sizes! A carat is equal to 200 milligrams (or .2 grams) and is the term to describe the weight of any gemstone, including diamonds. In jewelry pieces with more than one diamond, the carats may be described in terms of total carat weight (TW). This is the combined total weight of all the stones in the piece. It’s important to remember that a diamond’s value is determined using all of the 4C’s, not just carat weight.

Diamond Cut Education


One of the most defining characteristics of a diamond is its cut. The cut of the diamond refers the symmetry, polish and proportions of the diamond, not the shape (E.g. round, princess, emerald etc.) The cut determines how the diamond reflects light, making it the key to its sparkle. A diamond’s reflective properties are referred to as “fire” and “brilliance”. A diamond may have a perfect color and clarity but a poor cut worsens the diamonds appearance. The diamond shines and sparkles the most when it is ideally cut, allowing the light to travel through the diamond.


Diamond Clarity Education

The clarity of the diamond determines just how clear the diamond is, by referring to the absence of inclusions and blemishes. The clarity is determined on the size and position of any ‘inclusions and/or ‘blemishes’ on the diamond.

Below is the official chart of the GIA.

Grade:

Description:

Flawless (FL)

Absolutely no visible blemishes or inclusion under a 10x magnification.

Internally Flawless (IF)

No visible inclusions under 10x magnification.

Very, Very Slightly Included (VVS1 and VVS2)

Inclusions in a VVS1 diamond are so slight that they are difficult for even diamond expert to see under a 10x magnification.

Very Slightly Included (VS1 and VS2)

Inclusions in a VS1 and VS2 diamond range from difficult to somewhat easy to see, but only by a diamond expert with a 10x magnification.

Slightly Included (SI1 and SI2)

Diamonds of SI clarity contains Inclusions that are noticeable under 10x magnifications.

Included (I1,I2 and I3)

Inclusions are noticeable under 10 x magnifications which may affect transparency and brilliance. These inclusions can often times be seen without magnification.



Diamond Color Education

Diamond color actually means the lack of color. The scale below begins with the letter D, representing a diamond that is colorless. The chart continues to the letter Z, increasing in color. Top of Page
